Not: When in use, the initial gear cannot be set too high, the energy must be gradually increased from 01, and the maximum cannot exceed 50, otherwise the tube will be burnt out and sparks will appear. 

   Dear buyers, if you don’t know how to use it, please read the product introduction carefully or contact the seller for consultation!! 

   To the buyer: 

   1. This controller is mainly for friends who repair or use power banks, power tools, and airplane models. Generally, they can be welded with 3S 50C 5000mAH, or 12V 50AH or more batteries, which is very convenient. 

   2. Although the product has been designed to protect the drive of the MOS tube enough, if there is a phenomenon of explosive tube during use, just replace one. 

   3. If you have high welding requirements and the controller fails to meet his own welding requirements, please replace the welding power source when such a situation occurs. 

   After actual use, when the battery adopts 3S, 40C, 5000mHA, it can weld 0.1mm nickel-plated steel strip and 0.15mm nickel-plated steel strip perfectly. The welding needle needs to be ground into a round head, the pressing force is reduced, and it can also be welded. 

   When the battery uses 12V, 50AH, car battery, it can weld 0.15mm nickel-plated steel strip perfectly. Note that it is a car battery, not an ordinary lead-acid battery! ! ! 

 This kind of controller has a very large instantaneous welding current, 100 to 200A, and the heat inside the mos tube is also very large! Therefore, when testing the machine, the welding energy should start from the minimum, and the welding can be guaranteed. Don't set too large! The most important thing is to pay attention to the range of the power supply and the thickness of the welded nickel strip! If the nickel band is too thick, the tube will burn easily!

      Notice:  

         Please read the instructions in the package carefully,We donot provide extra technical support for it.   

       Please make sure you know how to config it before purchasing.   

   Features:  

   1. Wide selection of welding power supply: lithium battery power supply or 12V car battery. 

   2. The controller is controlled by a single chip microcomputer, and the output pulse is accurate to ensure the welding quality. 

   3. With LCD display screen, can display welding parameters. 

   4. The welding pen and the input line are connected by U-shaped cold-pressed terminals, which is convenient for disassembly and replacement. 

   5. Using automatic touch welding mode, while retaining the manual trigger interface, you can choose according to your own use. 

   6. The power board uses 2 Gusi copper to increase the overcurrent capacity. 

   7. Using 5*300A MOS tubes, non-disassembled MOS tubes. 

   8. The MOS tube driver adopts the imported special chip driver. The fastest MOS tube can be hit with 20nS. The switch is fast to prevent the explosion of the tube and the non-triode push-pull drive. 

   9. The MOS drive design adds a transient diode to protect the MOS and prevent the explosion of the tube. 

   10. 10AWG multi-filament flexible wire is used for the welding pen line and the input line to increase the overcurrent capacity. 

   11.The controller is mainly for welding nickel-plated steel strips from 0.1mm to 0.15mm. 

   12. A 25V10000uF high-frequency low-resistance capacitor is added to the power input for energy compensation, which increases welding stability. 

   Instructions for Use: 

   1: Power Connection 

   The controller comes with a 20cm long 10AWG input wire. One end has been crimped with a U-shaped terminal, and the other end has not been processed. Connect the crimped U-shaped terminal to the control power input terminal, and the other end is processed according to its own power supply. Do not connect the negative electrode wrong. 

   2: Switch on and off 

   There is a power switch under the control board. After pressing, wait for 3 seconds. After the buzzer drops, the LCD lights up and the boot is complete. Press the power switch again to shut down. 

   3: Screen description and parameter adjustment. 

   WELD ENERGY: 01-99 (adjustable by up and down keys) 

   INPUT: Display input power voltage 

   WELD WAY: Manual / Auto (Adjust via the "square label" button.) 

   4: Welding  

   Keep the welding pin clean. If the welding pin is polished into a round head, the welding effect can be improved. There are manual and automatic methods. 

   Specification: 

   Material: Metal 

   Input line length: app.20cm/7.87in 

   Length of welding pen: app.30cm/11.81in 

   Color: Red+Blue+Black 

   Battery: 18650 lithium battery(not included) 

   Quantity: 1Set 

      Note:  

     The controller comes with a 20cm long 10AWG input cable. One end has been crimped with a U-shaped terminal and the other has not been processed. Connect the crimped U-shaped terminal to the control power input terminal, and the other end is processed according to its own power supply.  

     There is an ignition switch underneath the control board. After pressing, wait 3 seconds. After the bell rings, the LCD screen lights up and the boot is complete. Press the power switch again to close it.  

     Please allow 1-2cm size errors due to manual measurement.
